PATENT WALTER S. GATES. OF DETROIT, MICHIGAN, ASSIGNOR TO INSULATING MATERIALS COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.

Drama AND BLEACHING MACHINE.

Application filed April 21,1924. Serial No. 708,028.

To all whom it may concern:

Be it known that I, WALTER S. GATES, a citizen of the United States of America, residin at Detroit, in the county of lVayne and S tate of Michigan, have invented certain new and useful Improvements in Dyeing and Bleaching Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates generally to dyeing and bleaching machines and refers more particularly to lifting devices for facilitating the removal of the yarn packages from the kiers of such machines. A

One of the essential objects of the invention is to provide the yarn packages with a strong and durable support that is adapted to be moved longitudinally of the yarn holders in the kier to facilitate the removal of 20 the yarn from the kier.

Another object is to provide a support of this type that may be conveniently raised or lowered and that is preferably guided within the kier by suitable means extending up- 2 wardly from the bottom of the kier.

A further object is to provide effective means for preventing the liquor used for dyeing from escaping at the lower ends of the yarn holders when the support is in low-' ered position.

With the above and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawing:

Figure 1 is a fragmentary elevation of a kier and showing my lifting device applied thereto; 1

Figure 2 is a top plan view of the lifting devices;

Figure 3 is an enlarged detail sectional view.

Referring now to the drawing in which like characters of reference designate corresponding parts throughout the several views, the numeral 1 designates a kier of a dyeing machine having a true bottom 2 and a false bottom 3, the latter preferably having vertical openings 4 therein through holders which the liquor used for dyeing is supplied to tubular yarn holders 5. As shown, these holders preferably threadedly engage the false bottom and are provided with apertures 6 through which the liquor is adapted to pass for dyeing the yarn packages 7 Any suitable means such as the caps 8 threadedly engaging the holders 5 may be used for retaining the yarn packages 7 in position on the holders during the dyeing operation.

To facilitate the removal of the yarn packages from the kier after the dyeing operation, I preferably provide a grid or plate 8 that normally rests upon thefalse bottom 8 of the kier beneath the yarn packages and that is adapted to be raised by means of rods 9 extending upwardly from the grid 8 at spaced points thereof. The grid may be any shape or size desired and may be constructed of any suitable material, such as brass, for supporting when raised, the weight of the wet yarn packages resting upon it. As shown, the grid 8 is preferably circular in form and is provided at spaced points with relatively large openings 10 for receiving the upwardly projecting yarn 5, While the lifting rods 9 are preferably located between the yarn holders and are threaded into the grid 8 and also into suitable attaching plates 11 that are rigidly secured to the upward face of the grid as shown in Figure 1 of the drawing. When the cover of the kier is raised, any suitable means such as the chains 12 of a suitable hoist may be connected to the eyes 13 at the upper ends of the lifting rods for raising or lowering the grid within the kier.

For guiding the grid while being raised or lowered, I preferably provide a pair of rods 14 that are preferably threaded into the false bottom 3 of the kier at spaced points thereof and that extend upwardly through suitable openings 15 in the grid 8' to points adjacent to the top 16 of the kier. Thus, the grid 8 will not leave the guide rods 14 when raised to a convenient position for unloading the yarn packages.

For preventing the liquor used for dyeing the. yarn packages in the kiers from escaping at the lower end of the perforated tubular yarn holders 5 without passing through the yarn and at the same time permitting the grid 8 to be raised when desired, I preferably provide the resilient packing discs 17 and the metallic washers 18. The packing discs 17 are preferably secured to the am holders 5 at the lower ends thereof an as shown in Figure '3' of the drawing, are preferably thicker than the grid 8, while the metallic washers 18 are sleeved upon the yarn holders so that they may move with the rid. When the yarn packages are removed from the holders 5 and the grid is "lowered, the washers 18 are adapted to rest upon the resilient discs 17 shown in Figure 3 of the drawing, which discs have been received into the openinglO in the grid. When the yarn packages are sleeved upon the holders 5, the

washers 18 supporting the yarn packages on the grid wlll compress the'resilient discs 17 as shown in Figure l of the drawing, to effeet a tight joint at the lower ends 'of the :yarn holders.

In use, when it is desired to remove the yarn on the holders within the kier, the cover 16 of the kier may be swung back on its pivots 19 and the caps 8 detached from the upper ends of the holders 5, whereupon the chains 12 of a suitable hoist may be attached to the eyes 13 of the lifting rods for raising the grid to the desired elevation for unloading the yarn packages, in which case the grid lifts the metal washers 18 and they in turn lift the yarn packages, the packing discs 17 remaining on the bottom of the kier.-

While it is believed that from the foregoing description the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the I scope ofwhat is claimed.

What I claim as my invention is:

1. In a machine of the class described, the combination with a kier, and yarn holders projecting upwardly from the bottom of the kier, of means in the kier for raising the yarn packages to facilitate the removal thereo from the yarn holders in the kier.

2.
